PETER THORHAUG, OF MINNEAIOLIS, MINNESOTA.

EMBALMING- INSTRUMENT.

Application filed May 16,

To a?! /1/1 710m it may concern Be it known that I. PETER THonrL-ino, acitizen of the United States, residing at Minneapolis. in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Embalm ing Instruments; and I do declare the followingto be a full, clear, and exact description ofthe invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in embalming instruments and moreparticularly to devices for injecting blood solvent into the veins andfor draining the blood therefrom. Heretofore, in a great majority ofcases, separate operations have been necessary to first inject the bloodsolvent into the veins and to then drain the blood and solventtherefrom, it being often necessary to repeat these operations severaltimes before the required results are obtained. This is not only arduousand requires a great deal of time, but there is danger of soilingarticles around the corpse, as well as otherwise adding greatly to theduration of the embalming operation.

One object of my invention is to provide a simple, inexpensive andeasily operated device by whose use. the blood solvent may be injectedinto the veins and the blood drained therefrom at the same time, novelprovision being made however whereby the blood outlet may be totally orpartially closed whenever it is desired to withdraw a greater or lessamount of the blood.

In carrying out the above end, I pass a solvent-injecting tube slidablythrough a drainage tube and a further aim is to make provision forprojecting saidy solvent-injecting tube a considerable distance fromsaid drainage tube, whereby the solvent may be forced a greater distanceinto the veins than is possible with the instruments now in common use.

With the foregoing and minor objects in view. the invention resides inthe novel construction vand association of parts herein! after describedand claimed, the descriptive matter being supplemented by theaccompanying drawing:

Figure l is a side elevation of an embalming instrument constructed inaccordance with my invention.

tional view through'the greater part of the Y device.

Figure 3 is a transverse see-tional View as indicated by line 3-3 ofFig. 2.

Figure 4 is an enlarged detail sectional view through the drainage tube,showing an elevation of the solvent-injecting tube and its tip.

Figure 5 is a view similar to a portion of Fig. 2 but illustrating themanner in which the blood outlet may be closed whenever desired.

In the drawing above briefly described,v

the numeral l designates a tubularv drainage tube formed of rear andfront'sections 2 and 3 respectively, said rear section being preferablyof somewhat larger diameter than the front section in order to form ahandle which may be more conveniently used than if it were offsmallersize. The section 3 may be straight or curved as occasion may dictateand this section is preferably detachably connected with the rearsection 2, for instance by screw-threads 4, so that whenever necessaryya shorter or tube, the front section 9 of said tube being t preferablyof much smaller diameter than the rear section, since it must befprojected into the vein. y The two Vsections- 8 and 9 are detachablyconnected with each other by any suitable means such as thescrew-threads 10 shown in Figs'2 and 5. The rear section 8 servesasrmeans for projecting the front end of the Section5) to the necessaryextent beyond the front endof the tube section 3, or for withdrawingsaid section 9 within the section 3 as seen in Fig. 4 so as `tofacilitate insertion of the entire device into a vein. lIn order toprevent clogging of lthe'tube 1 as it is being forced into the vein, thefront terminal of the tube section 9 is provided with a plug 11 whichthen closes the front end of the tube section 3 as seen clearly in Fig.4. The rear end of the tube section ,8 is adapted for connection with arubber tube leading from a receptacle containing the blood solvent orother liquid to be injected into the vein, while the front end of saidtube section is provided with a valve piston 12 which is adapted tocontrol the outlet branch 5.

When operating the device, the inner tube 8 9 is pulled outwardly to theextent shown in Fig. l, thereby positioning the plug 1l in the front endof the tube l to prevent congealed blood or fibrous tissues fromclogging the front end* of the device. Then the tube section 3 has beeninserted the proper e tent,vthe supply of solvent liquid is forcedthrough the inner tube and the latter may be forced inwardly to anyrequired extent beyond `the front end of the tube section 3, The`congealed blood is thus dissolved and will How through the tube l andits branch 5 to the receptacle provided for its reception. If it isdesired to continue the injection of solvent while temporarily lesseningthe discharge of blood, the tube section 8 is forced inwardly to theextent shown in Fig. 5 whereby the valve l2 will close the branch 5.Furthermore, by proper manipulation, the branch may be opened `to anydesired extent so that the ratio ofthe ingoing liquid to theoutgoingblood, may be controlled to produce the most advantageousresults.

I After use, the device may be quickly and easily disassembled forcleaning,due to the screwthreaded connections 4 and 10 and tbe threadedgland' which receives the tube section 2. It is to be Vfurther notedthat by employingthe threaded connections 4 and 10, tube sectionsV 3 and5 of differentdiameters o1' lengths may be provided, so that the devicemay be perfectly adapted to the operation to be performed. Attention mayalso be directed to the fact that by tightening the glandt, the packingring 7 is forced to hold the rear tube section 8 in any position towhich itinay be adjusted, this being often of great advantage since theoperator does not thenhave to hold said tube section with one hand.`

'From the foregoing taken in connection with the accompanying drawing,it will be seen kthat whilemy invention is very simple and inexpensive,1t will vbe highly efficient and in every "way ldesirable, permittingsimultaneous in'ection of blood solvent and draining of b ood, Without"any danger ot' soiling the clothing or any articles around the corpse.

Sneeexcellent results have been obtained from the exact fdetailsdisclosed, they are preferably followed." Itis to be understood howeverthat within the scope o'lr the in 'vention as claimed, numerous minorchangesl may be made and 'furthermore that the device may be constructedin its entirety at the factory, or provision may be made for convertingthe draining tubes now on the market, into the improved device.`

I claim:

l. A. solvent injecting and vein draining device comprising a tubularbody having a stuling box at its rear end and a lateral outlet, saidbody being provided with an outer forwardly extending tubular needleo'l' uniform diameter throughout its length and adapted to be insertedin a vein of a corpse, an inner tubular needle slidable within saidfirst named needle and having a rear end portion passing through saidstufiing box,

the portion of said inner needle received in said outer needle being ofless external diameter than the internal diameter ot the latter andbeing adapted to be projected forwardly from sai-d irst named. needle tovsupply blood solvent tothe vein while draining blood from the latterthrough vthe outer needle.

2. A. solvent'injecting and blood draining device comprising a tubularbody having a stuffing box at its rear end and a lateral outlet, saidbody being provided with an outer forwardly extending tubular needlelongitudinally curved and of uniform diameter -throughout its lengthYfor insertion into a vein of a corpse, a rigid tubular body-slidable.through said ustuliing box, and an inner resilient needle extendingforwardly from said rigid body through said outer needle vin spacedrelation thereto, said inner needle being adapted to be projectedforwardly from said outerneedle to inject blood `solvent into the veinwhile draining blood from the latterthrough the Vouter needle.

3. A solvent injecting and blood draining `device comprising a rigidtubular handle having astuiing box at its rear end and a lateral. outletnear its lront end, a rigidtube section slidable through said stuiflingbox, au outer tubular'needle threaded-in and eX- tending forwardly'fromsaid handle, and an inner tubular needle within and spa-ced 'from saidouter needle, said inner needle being threaded at its rear end into saidtube section, said inner needle being adapted' to be projected forwardlyfrom said outer needle to inject blood solvent into the `vein -whiledrainingblood from the latter through the.
